Symptoms

When the command "tmsh show sys cpu" is executed, the output has "Util% (last 10 sec)" field displayed with incorrect information for the total column.

Impact

The displayed data is not correct. Instead, the system is displaying the usage ratio which is calculated in an entirely different manner.

Conditions

This occurs when the command "tmsh show sys cpu" is invoked.

Workaround

You can use the tmctl command to display the 5 sec average ratio which is what the output should be. The command is: tmctl cpu_info_stat -s five_sec_avg.ratio This provides the workaround to the output for the tmsh command "tmsh show sys cpu".

Fix Information

"Util% (last 10 sec)" field output in "tmsh show sys cpu" when 5 second average is computed now displays the 5 seconds average data.
